WIDE FABRIC PREPARED TO BE SLIT AND METHOD OF PREPARING THE SAME.

Application filed January 18, 1928. Serial No. 247,473.

The present invention is related to the art". of slitting wide fabricsinto narrow strlps and is articularly useful in making typewriter ribons and the like, my improved method and apparatus effecting aconsiderable sav'-.

ing in the fabric-in slitting the same, and more eflicient results beingobtained.

In the manufacture of typewriter ribbons, for example, under presentmethods, a roll of cloth is clamped upon an arbor, the arbor and clothroll then being rotated as a rotatable cutter is brought into contactwith the cloth, thereby slitting the cloth to the desired width. Thismethod, however, is unsatisfactory commercially owing to the difiicultyexperienced in properly holding the roll so that the same can be slitsatisfactorily ad'acent the clamped end, resulting in waste 0 material,uneven cutting and generally unsatisfactory results. a

The present method and apparatus provide for retainin the roll of clothin place with suflicient sta ility and rigidity to permit of the clothto be slit or cut evenly and practically the entire roll to be utilized.

In the accompanying drawings,

Fig. 1 is a view in sectional elevation of an apparatus by which myinvention may be practiced; and

Fig. 2 is a view on the line 22 of Fig. 1 lookin in the direction of thearrows.

In t e practice of my invention a strip of adhesive paper, tape or othersuitable somewhat stiif material 2 is wrapped about the drive end of aroll of fabric 3 to be .slit, as illustrated in Fig. 1, this paper 2being applied so that a portion thereof will project beyond the driveend of the roll to provide a cup-shaped depression 4:.

A spider 7 is then placed in the depression thus formed, this spiderbeing provided with a hub 8 which is slipped over the card board tubing9 on which the fabric is rolled. With the roll standing on end and thespider 8 in place wax is poured into the depression 4, this wax or othersuitable material which is designated 5, flowing between the turns orwraps of the roll to unite the spider and roll into a solid unitarystructure. The-roll 3 and spider 7, are then slipped over the arbor 10,and the hub 8 of the spider attached to the drive for the arbor 10 by aset screw 11. The roll 3 may then be rotated and a rotatable cutter 12brought into operative relation thereto to slit the cloth as I haveindicated a method and apparatus which great y.facili-' tates theslittin of wide fabrics into narrower widths, provlding a method and aparatus whereby not only may the entire roll practically, be utllized,but the roll will be sustained with sufiicient rigidity and stability toenable the desired even slittin to be produced, thereby eliminating thefifliculties experienced heretofore in this art.

What I claim is 1. In the slitting of wide-fabrics into narrow widths,the method of preparing the fabric for slitting which oonslsts 1napplying an annular extension to a roll of the fabric and filling thedepression thus formed with a self-hardening material thereby to unitethe extension, roll and the ends of the wraps of the materialconstituting the roll into a solid rigid structure.

2. In the slitting of wide fabrics into narrow widths, the method ofpreparing the fab ric for slitting which consists in applying an annularextension to a roll of the fabric, attachin a coupling member to the endof the roll Within the depression thus formed by placing the couplingmember within the depression and filling around the same with aself-hardening material while allowing this material to flow between thewraps constituting the roll.

3. In combination a roll of material to be I depression at the roll end,a self-hardening material inisaid depression, and a coupling memberattached to the roll by said self-hardening material.

5. In combination a roll of material to be slit into narrower widths, anextension on said roll providing a depression at the end of the roll, aself-hardening material in said depression and contacting with thematerial of the roll and lying between the ends of the Wrap composingthe roll and a coupling member embedded in said self-hardening material,whereby the coupling member is attached to the roll and the end of theroll converted into a rigid structure.

This specification signed this 16 day of January, 1928.
